BREECH-LODING GUN.

SPECIFICATION forming partof Letters Patent No. 429,811, dated June 10,1890.

i Application filed November 9.1889. Seriallio. 329,797. .(No model.)

To a/ZZ whom it may concern.-

Be it known that we, OLE HERMAN J oHAN- NES KRAG and ERIK JRGENsEN,subjects of the King of Norway, residing at Kongsberg, Kingdom ofNorway, have invented certain new'and useful Improvements in MagazineFire-Arms; and we do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters origures of reference marked thereon, which form a part of thisspecification.

Referring t0 the drawings, Figure l is an isometric view of a portion ofa gun embodying my invention, the' magazine-gate being shown fully openand thebreech-bolt drawn back. Fig. 2 is a like view, thebreech-boltbeing removed and the magazine-gate closed. Fig. 3 isa longitudinalaxial section of the gun, the breech mechanism being shown inthefull-cock position.

Fig. 1 5 is anisometric view of the cartridge-m agazine detached from the gun. Fig. 16is a horizontal section thereof, the gate being shown as partly open.Fig. 17 isv an inner face view of the magazinegate. Figs. 18 and 19 aredetail views of the ejector-lever and the stop-lever for the magazine,respectively.

The invention relates to repeating breechloadi fr guns, and has for itsobject certain improv ments whereby the breech mechan- -ism issimplified in its construction vand the efficiency of the gun materiallyenhanced.

The invention consists, essentially, in certain novel features ofconstruction, arrangement, and co-operation of parts of the breechmechanism; also,in the combination, with the receiver, of amagazine andmeans for feeding the cartridges therefrom to the receiver, sub-`stantially as hereinafter described, and asset forth in the claims.

In order that our. invention may be fully understood, We will describethe several parts thereof separately and then their co-operation. A l

Those parts common to all fire-arms of this class comprise the stock S,the barrel B', the

trigger-guard T', the vtrigger' T, and Sear S2,

introduction of the cartridges-when used as a single loader, and tothrow the shells 'out laterally, so as notto interfere with themarksman. A portion of the under side of the receiver is flat, as shownat fr, Fig. 11, and-fin said under side are formed screw-threadedsockets r for the screws s, Fig. 4, by means of which the magazine issecured in position, and with a like socket rrzfor the screw s', Fig. 3,by means of which the forward tang of the trigger-guard is secured. Atits rear end the receiver has a tang R', andl is secured to the gunstockS at that point by means of a screw s2, that also serves to secure therear tang of the trigger-guard T.

R2 is the rear stop-lug, usual in this class of guns, and serves tolimit the rearward motion of the breech-bolt and guide thesame in itsmovements. The'front and rear faces of the lugs are planes incliningrearwardly from the base of the lug to the upper edge thereof, saidfaces forming a part of a helical screw-thread.

In the left-hand side of thel receiver is formed an opening orlongitudinal slot l of less widthnat the rear than at the frontend,

IOO

. provided with a longitudinal bearing', in which.

and in a recess formed partly in the lower wall of said slot and partlyin the rear end of the receiver is pivoted a gravity shell-ejector E.The upwardly-turned forward end e of the ejector lies normally flushwith the inner face of the receiver, and at i'ts rear end said ejectorhas a heel or projection e', that projects normally into the receiver. lThe forward end of the slot 1 in the receiver merges into a taperingrecess 2, and decreases gradually in .depth outwardly or vforwardlytoward the breech-chamber C to guide the bullet end of the cartridgeinto the said chamber, Figs. 1, 2; and 4.

At its rear end the lreceiver is recessed and lis seated a stop-lever L,that has a 'thumbpiece Z, Figs. 2, 4, 10, 11, 'and 19, said lever beingsplit, as shown in Fig. 19, and is held in its bearin g by the pressureexerted by the spring-arms l l2. The longer arm l projects into slot 1and lies normally in av recess 3, Figs. 11 and 12, formed in the face ofthe upperwall of slot 1. When the lever is turned into the positionshown in dotted lines in Fig. 4, the arm Z will move into the'slot 1 andpresent its dat face thereto.

At the bottom of the receiver at its front end is formed a recess 4 forthe locking lug or shoulder ba on'the breech-bolt, and at the front endof the left-hand wall of said receiver is formed a ledge or projection5, Figs. 1, 2, and 4, that forms an abutment for a shoulder e at the,forward end of the shell-extractor.

In t-he breech-chamber C is formed a recess 8, the upper wall 9 of whichinclines forwardly for the reception of the extractorhook.

The breech-boZt.-The breech-bolt B, Figs. 1, 3, 5, 8, and 9, is a tubeWhose -front end is closed, and in said closed end is formed aninwardly-flaring axial passage 6 for the firing pin or nipple. At thesaid forward end the bolt has the locking lug or shoulder b3, that takesinto the recess 4, above referred to, when the bolt is turned into aposition for firing The bolt B is also provided with a longitudinal ribb4, that serves to limit its rotary movement in either direction withinthe receiver, and at -its rear end the bolt has the usual handle b5. Atsaid rear end is formed a slot or recess b, one of the walls ofwhichnamely, that on-the right hand formed by the handle-is straight,while the left-hand wall bT is curved laterally, Figs. 1 and 8.

From the handle b5 a locking-shoulder bg extends about one-third aroundthe bolt, said shoulder tapering rearwardly and having formed thereinnear the left-hand edge a longitudinal locking notch or recess b, Fig.The shelZ-extfractor.-The' sh ell-extractor F. is connected by a h ingeor pivot-joint 021 with the forwardly-proj ecting arm or lu g c of acar'- rier C', which consists'of a tubular section c c2. The rearport-ion c of tubular carrier C is slotted longitudinally, and is'ofgreater dii: ameter than the breech-bolt, while the front portion c2 isof less diameter and is fitted tightly within the rear end of said bolt.

The shell-extractorE has a hook e, the

upper face of which is inclined to fit the re v 4 provided wherein it'is securely held against vertical displacement.

The frz'ng-pn.-The firing-pin, Figs. 3, 5,

-and14, has at its enlarged rear or handle end the full-,cock notch f;or said pin maybe provided with both a full and a half-cock notch ffrespectively, as shown in Fig. 5.

The firing pin or bolt in all bolt-guns with which we are acquainted ismade of a single piece, and it frequently happens that thestriking-point is broken olf in use or by accident, thus requiring-a newpin or bolt to be applied. To avoid this, we make the said pin or boitof two parts, detachably connected, of which part F is the strikingpoint or nipple and part F -the bolt or pin proper. The strik ing pointor nipple F has a tubular portion f2, about onehalf of which is cut awaylongigitudinally, leaving a collar or sleeve f 3, against which abutsoneend of the spring S, that impels the firing-pin within the 'breechboltB, the other end of said spring abutting against the end of 4the tubularportion o2 of the y extractor-carrier C', Figs. 3 and 5. At the forwardend of the tubular portion of the nipple is formeda socket-bearing f4for the head f 5, formed on the attenuated extension f6 of thefiring-pin, whereby both parts are detachably connected. Should thestriking point or nippleF break, the part F can be readily removed fromthe part F and another substituted.

The operation of the gun is as follows: Supposing the breechmechanisxnIto bein the position show-n in Figs. 3 and 5, with theexshell, the handle bsof the breech-bolt lyingin the recess 10, Figs. 1and- 2, behindlug R2, and

the lug b3 in recess 4, thus locking the breechbolt securely 'inposition, as the firingpin F F is released by pulling on the trigger Tand moves ,forward under the stress of its spring S the arm F?, in whichis formed the full-cock notch lyingin the slot in the tubular portionAcof the extractor-carrier C', enters the recess b along the straightface thereof, the striking point or nipple exploding the charge. If, thebreech-bolt B is now turned with its handle b5 in va vertical position,or approximatelyso, the inclined face or wall b7 of theA rccessb'in thebolt B will op-v erate on the `forward end of the arm F" and move thefiring-pin F back against the stress of its vspring S', while therecessbf is moved IOO I5 tractor-hook 621 over the rim of the cartridge-429,811 j lt,

out of "register with the said arm F2, so thatr the breech-chamber C andfacilitate the rearward motion of the breech'- bolt. As the breech-boltis turned, as described, the lug b2, as well as the handle b5, will moveout of their locking-notches, so as to completely unlock thebreech-bolt, as will be readily understood. The breech-bolt may now bepulled back, when the empty shell held by the extractor-hook willencounter'the projecting upturned end e of the shell-ejector E, by whichit is thrown out of the receiver. As hereinbefore stated, the heel e ofthe shell-ejector projects normally into the receiver, so that as thebreechbolt B moves in and outof the receiver it (the bolt) will bearupon the heele of the ejector, thereby lifting the forward end ethereof, so that said end 'e will projeetinto said receiver. Inasmuch asthe to-and-fro movements of the bolt B, which fits snugly int-o thereceiver, would Abe impeded by the projectingend e of the ejector E,said bolt is vprovided with a .right-angled groove B2, Fig. 9, thelongitudinal branch b of which merges at its rear end into aperipheralbranch Z1', that extends partly around the said breech-bolt. The forwardend b2 of the longitudinal branch l) of -groove B2 decreases graduallyin depth, so as to allow the end e' of the ejector to freely slide intoand out of it. When the breech-bolt B is in the position just described,and as shown in Fig. 1`, the heel e of the ejector E lies in the shallowouter end b of the branch b of groove B2, the rear end of the ejectorbeing thus depressed, while its forward end e is lifted and projectsinto the receiver. A fresh cartridge may now be inserted into thereceiver and the breech-bolt moved*forward, the;eartridge being carriedalong by the bolt and pushed into the breeehchamber C, the upperinclined face of the extractor-hook e21 bearing against thecorresponding face 9 of the recess 8 in the breechchamber wall. XVhenthe longitudinal rib b4 of the breech-bolt has cleared the lug R2 andsaid bolt is turned to the right by means of the handle b5, the boltwill be forced home by the outer face of the lug R2 opera-ting on therib b4, said outer face being also curved rearwardly, so as to form aninclined surface,

as hereinbefore stated, thereby forcing the extractor-hook @21 intoengagement with the rim of the cartridge. The returning of thebreech-bolt into a tiring position also brings the recess b in line withthe arm F2, in which is formed the full-cock notch f, and if the triggerwere held back the charge would be exploded; but as the breech-bolt B ismoved into theposition of firing the scar S2 engages the full-cock notchf and holds the ring-pin against forward motion until released bypulling the trigger. As'the breech-bolt B is moved forward the heel ofthe ejector enters the branch b of the groove B2, thus allowing theforward end e of the ejector to drop down flush with the inner face ofthe receiver. On the other hand, whenl the bolt B has been fully pushedinto the .receiver and is turned to a position at right angles to thatshown in Fig. 1, the heel e of the ejector will lie in the peripheralbranch b of the groove B2. The shell-extractor Ef is a spring-arm, thestress of which is exerted downwardly, so that the hold of theextractor-hook 621 on the cartridge-shell is not released until this isdone forcibly by the ejector E. This downward stress of theshell-extractor E may be increased by an auxiliary spring-arm 12, Fig.5, the front end of which bears against the inclined underside oftheledge or projection 5 when the parts are in their respectivepositions for firing.

The object of pivoting the shell-extractor to the carrier C is tofacilitate the removal of the breech-bolt from the receiver, which couldnot be done otherwise, for the reason that the bolt cannot be turned tobring its locking-lug b2 on a line with the slot at the rear end of thereceiver. By pivoting the extractor tothe carrier it can be lifted abovethe lug R2 and turned to one side, when the bolt may be turnedsufficiently to bring its locking-lug b2 on a line with the slot formedby lug R2 and the opposite wall of the .receiver and then withdrawn fromthe latter.

In Figs. 5 and 6 we have shown a modified arrangement of theshell-ejector. The locking-lug b3 is chambered. In the chamber thereofis seated an ejector-pin P, so as to move freely therein. On the lug R2,of the receiver R is a stud or projection 14, Fig. 7, that yim- `pingeson the head1) of pin P when the breechbolt B is moved to the limit ofits backward motion, causing the forward end of the pin to strike thecartridge-shell and ej eet it from the receiver. e

XVe have described the gun as a single loader, and it maybe so used, thecartridges in the magazine M being prevented from entering t-he receiverbythe stop-lever L; but when used as a repeater said lever is turned outof the way, as hereinbefore described.

` The mammina-The magazine M, Figs. 1, 2, 3, 4, 7,15, 16, and 17, is anopen casing having a flat bottom mf, that merges into annpwardly-curvin'grear wall m2, partly inelosing the left side of thereceiver R, below which the magazine islocated, the receiverconstituting the topl ot the said magazine. The right side or front ofthe magazine is closed by a gate G, held in a closed position by .meansof a latch that is constructed and operated as follows: The spring latchor lever A is secured tothe. upper wall g2 of thegate G by means of ascrew s2, and is adapted vto engage a loeking-not'eh'N. On said latch Ais secured or formed a horizontal journal a,

IOO

Fig. 7, that fits into a bearing or eye (l, formed on the stem of athumb-piece D, that is pro-l vided with a bearing-ilange d', so thatwhen the 'thumb-piece is tilted toward the right the spring-latch islifted out of the lockingnotch N. The gate is pivoted to the'magazine bymeans of a pivot-screw S3, and in its front .wall g3 has an opening, thefront and rear walls of which incline outwardly and forwardly, '(seeFig. 16,) and in said opening is seated. the heel h of a strong springH, having an arm h, formed at right angles thereto at its free end, thatlies in a concave notch or recess 0 of a feed-lever O, pivoted to aIstud'or pin o', depending from the top of the gate.- The lever O has at,its outer end a spoon-shaped head O, to which is pivotally connectedthe feed-plat-e Q, said plate having a central aperture provided =withbearings for a journal or pivot-pin q, Fig. 16, so that as the levermoves under the stress of the spring ll from the position shown -in thelatter figure to that shown in Fig. 15 the feedplate will be able toassume such position as to remain at all times fully in contact with thecartridges. On tli-evback the feed-plate is provided with a longitudinalgroove q', in which the lever O lies when the parts are withdrawn in thelid or held therein by the cartridges in the magazine, so that saidparts fold together compactly. On one side of the fulcrum o of lever Ois an abutment ct', that projects from the magazine behind the short armo2 of lever O, which short arm, as shown in Fig. 16, is in contact withsaid abutment c', so that as the gate is swung farther open the'leverwill be forced against the stress of its spring H into or against thegate, as shown in Figs. 1 and 17. When the gate is closed, the fulcrum oof lever O will lie so far to the left or rear of the abutment-namely,about at 021, Fig. 1G-as to allow said lever to swing fully into themagazine, as shownin Fig. 15. The spring l-I therefore exertsits fullpower on the lever O only when the magazine-gate G is closed, while whenopen the stress of the spring is taken up by the abutment cz.

It is obvious that if the magazine is lilled with cartridges acontinuous pressure is exerted thereon by the feed-plate Q. The foremostor left-hand cartridge sliding up the curved wall m2 will lie along theslot 1 of the receiver. The magazine-gate G is or may be provided with astop-lip g5, as shown in Fig. 1li, to limit its outward movement.

IVe have hcreinbefore stated that the rear end of the slot 1 in thereceiver R is narrower than the front end, but is of such width as toallow a portion of the' rim of the cartridge-shell to project into thereceiver in the path of the breech-bolt .il when the stop-lever L isturned out of the way, as shown in dotted linesin Fig. 7. As thebreech-bolt is moved forward it impin ges upon the proj cctingend of theshell and carries it along, the bullet sliding up the inclined face L atthe forward end of the slot, at which time the rear end of the cartridgehasalso reached the wider portion of the slot and will be forced int-othe receiver by the feed-plate Q or by the next succeeding cartridge.The inclined face 2 guides the bullet end of the cartridges into thebreechchamber, as hereinbefore stated. In order thatv the last cartridgein the magazine may be properly fed to the receiver-,which can only takeplace by the feed-plate assum; ing a more or less inclined position topermit it to move up `sufficienti y toward the slot 1, we form thefulcrum-bearing 0 for. the lever O of an elongated slot ol, so as topermit the lever and plateto rake the inclined position shown in dottedlines in Fig. 7.

In guns of this description it is desirable to provide means for lockingthe firing pin against forward movement to prevent tlie accidentaldischarge of the gun. Ve have hereinbefore stated that the breech-bolt Bhas a rearwardly-tapering shoulder D8, in which is formed a longitudinalnotch or recess hf that is substan tially semi-cylindrical incross-section. In the extractor-carrier C is formed a bearing, in whichis seated alocking-'pin C2,thatproj ects into the recess formed in thecarrier for the accommodation of the shoulder bs on the breechbolt. Thatpart of the pin that lies within the recess of the carrier C is cut awayon a line corresponding with the inclination of the shoulder bs, (seeFig. 3,) so that when the flat face of the pin faces the shoulder thebreech-Y bolt can turn freely in the carrier. When,

thumb-piece 022, the rounded portion will enter the recess b9 and lockthe bolt against rotation. This can only take place when the bolt is ina given position-namely, in that in which the firing-pinis at full-cock, so that when the `bolt-handle b5is turned to the firing posi`tion and the locking-pin C2 is also turned the bolt is locked againstrotation in the receiver.

thumb-piece c22 being then in the position shown in full lines in Figs.1, 3, 8,and 9thus allowing free motion to the iiring-pin- Vhen, however,the thumb-piece 022 is turned up to lock the bolt, the cut-away portionof the sleeve bearing moves out of register with said handle end of thefiring-pin, the sleevebearing lying in front of the shoulder f2s, thuslocking the pin against movement.
